DISPENSING-CAN.

SPECIFICATION forming part of Letters Patent No. 722,099, dated March 3,1903.

Application filed September 4, 1902. Serial No. 122,116. (No model.)

To all whont it may concern.-

Be it known that I, HOLMAN GOULD, a citizen of the United States,residing at Auburn, in the county of Androscoggin and State of Maine,have invented a certain new and useful Dispensing-Can, of which thefollowing is a specification, reference being had therein to Thisinvention relates to dispensing-cans adapted for delivering in suitablequantities any liquid, such as the various kinds of oils, includingkerosene, naphtha, gasolene, and the like.

One of the principal objects of the present invention is to produce acheap, durable, and effective dispensing can in which the importantpartssuch as the pump mechanism, pump-cylinder, and the air and oilpipes-are so constructed and arranged as to be readily removable,thereby facilitating the repairing of the can and the several partsthereof. By these means the life of the can may be greatly increased andthe can as a whole kept in repair at a nominal cost.

A further object of the invention is to so construct a can of thecharacter described as to economize in the cost of production.

A further object is to provide reliable means for excluding water fromthe can either when sitting upright or lying on a side and alsopreventing the escape of oil from the can.

With the above general objects in view the invention consists in thenovel construction, combination, and arrangement of parts, ashereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a central vertical sectionthrough a dispensingcan constructed in accordance with the presentinvention, showing the same closed and ready for transportation. Fig. 2is a horizontal cross-section on the line 2 2 of Fig. 1. Fig. 3 is adetail elevation showing the manner of fastening the cover on the top ofthe can. Fig. 4, is an enlarged detail section showing the air-sink andthe relation thereof to the can and the oil-pipe.

Like reference-numerals designate corresponding parts in all figures ofthe drawings.

Referring to the drawings, 1 designates the body of the can, which forthe sake of cheapness may be constructed of tin and by preference isof'cylindrical shape, being closed at the top by a wall 2 and at thebottom by a wall 8, the bottom wall 3 being held at an, elevation by aflange 4, which may be formed by extending the cylindrical body of thecan below the bottom 3, as shown in Fig. 1. The flange 4 provides roomfor the air and oil sinks, hereinafter described, and prevents the samefrom coming in contact with any surface upon which the can may rest whenstanding upright.

The top 2 is provided with an opening 5, and the bottom 3 is providedwith a similar opening 6 in line with the opening 5, said openings beingadapted to receive a pumpcylinder 7, which is preferably double,consisting of two thicknesses of tin or other material arranged onewithin the other and preferably in contact, as shown. The length of thecylinder is such that it extends entirely through the body of the canand also through the openings 5 and 6, projecting far enough below thebottom 3 to be soldered to the outside of the bottom, as indicated at 8.At the top also the cylinder is soldered to the can and projects aconsiderable distance above the top of the can and is covered by acap 9,having a surrounding flange 10, which extends down upon the outside ofthe projecting portion of the cylinder. The cap 9 rests directly on thetop edge of the cylinder and reaches to or nearly to the top of the can,where it is provided with eyes 11 to receive fastening devices 12, suchas pieces of wire, which also connect with other eyes 13 on the top ofthe can, the cap 9 being thus securely held in place. The cap may,however, be readily detached by removing the tie-wire or fasteners 12.

The cap 9 is provided with a central collar let, which extends bothabove and below the body of the cap, as shown in Fig. 1, to provide along bearing for the stem 15 of the pump and also to form an effectiveclosure for a venthole 16 in the stem 15, which is tubular throughout.The upwardly-projecting portion of the collar 14 is designed to enter acorrespondingly-shaped recess 17 in the pumphandle 18, which is fastenedupon the upper end of the stem 15 and closes that end of the stem. Whenthe pump is at the lowest end of its stroke, the upper portion of thecollar 14 is received in the recess 17, and should the can be standingout in the rain no water can find its way into the pump-stem, as it willbe stopped by said collar, taken in connection with the handle, whichfits over the collar. On the lower end of the stem 15 is a piston 19 ofany suitable construction. No valves are necessary in the constructionof the pump, as by placing a finger over the vent-hole 16 and operatingthe pump the air passing in through the top of the pump-cylinder and bythe piston 19 will be forced out of the lower end of the pump-cylinder,which is closed by the end wall 20, having an upstanding nipple 21,through which the air passes and by means of which any moisture or wateror dirt which may possibly find its way into the cylinder is preventedfrom getting farther, the upstanding nipple 21 forming a trap.

Extending through the body of the can is an air-pipe 22, which ispreferably of lead for the sake of durability and to prevent corrosion.The pipe 22 extends entirely through the can from top to bottom and alsothrough the top and bottom 2 and 3 of the can and sufficiently beyondthe same to be soldered or otherwise secured thereto, as shown at 23. Byremoving the solder 23 the pipe 22 may be removed from the can whenneeded for any purpose. Covering the lower end of the pump-cylinder andthe lower extremity of the pipe 22 is an air-sink 24, which isdetachably secured, as by solder, to the bottom 3, said sink serving toconvey the air from the pump-cylinder to the air-pipe 22. Adjacent tothe upper end of the pipe 22 the top of the can is provided with a smallair-inlet hole 25, and a V-shaped tubular connection 26 is de tachablyconnected, as by solder, to the top of the can, one end of theconnection 26 covering the upper end of the pipe 22, while the oppositeend of the connection covers the airhole 25. Thus air compressed by thepump is forced through the pipe 22 into the upper portion of the can, soas to force the contents of the can outward through the discharge-pipe,hereinafter described. By making the airinlet hole 25 quite small theair passes backward into and through the pipe 22 very slowly and to thatextent assists the operation of the pump, the hole 25 acting somewhat inthe manner of a check-valve. The connection 26 is provided intermediateits ends with an airshut-olf cock 27. through the body of the can fromtop to bottom, corresponding exactly in length and manner of fasteningwith the air-pipe 22, said pipe 28 being preferably soldered, as shownat 29, to the top and bottom of the can. Adjacent to the lower end ofthe pipe 28 the bottom of the can is provided with an oil-hole 30, andsaid hole, together with the lower end of the pipe 28, is covered bymeans of an oilsink 31, which, like the air-sink 24:, is detach- Anoil-pipe 28 also extends able for giving access to the pipe 28, theoilsink being preferably soldered to the bottom of the can to facilitateits removal. Oommunicating with the upper end of the oilpipe 28 is adischarge-nozzle 32, having an elbow 33, which fits over the upperdischarge end of the pipe 28, the nozzle and its elbow being providedwith a shut-off cook or valve 34, which is opened by turning the nozzleout- .ward to the position shown in Fig. 1 and closed by turning saidnozzle inward over the top of the can, under which latter adjustment thenozzle affords no projection beyond the side of the can. The elbow 33 ofthe dischargenozzle is sufficiently large to fit over the soldered upperextremity of the oil-pipe 28.

35 designates a raised collar surrounding the usual filling-point of thecan, the same being closed by a fillingcap 36. It frequently happensthat the filling-cap corrodes and is difficult to remove, and in orderto overcome this and facilitate the removal of the cap a sleeve 37 isextended diametrically along the top of the cap and secured firmlythereto, so as to receive a pin or nail or other convenient implementwhich may be used as a lever or handle for turning the cap on or 01f.

In order to still further prevent the admission of water to thepump-cylinder, I make use of what may be termed a pump-cover 38 of asize and shape adapted to fit over and entirely inclose the upper end ofthe pumpcylinder, the pump-cap, and the handle, said cover beingcylindrical in shape and closed at its upper end. At the lower edge thecover 38 is provided at one side with an eye 39, which connects with astaple 40 orits equivalent on the top of the can and forms a hingedjoint. At the opposite side the cover 38 is provided with another eye llto receive a hook or other suitable fastener 42, connected with the topof the can. The cover is thus securely held in place for transportation,but may be readily thrown back in order to operate the pump.

In operation the cover 38 is thrown back and the pump is operated tocompress air, the finger of the operating-hand being held over thevent-hole 16. The air is forced into the upper portion of the can, andthe liquid is thereby forced upward into the pipe 28. By turning thenozzle 32 to the position shown in Fig. 1 the oil is forced out-wardthrough the nozzle and into the lamp or other receptacle placed beneaththe same. If desired, while the nozzle 32 is closed any amount of airmay be forced into the can and the shut-off cook 27 closed. This retainsthe air in the can, so that without doing any further pumping thedischarge-nozzle may be swung outward,when the air-pressure willautomatically force the oil outward through the nozzle.

The can is economical in construction and all parts are accessible forrepairs. The pipes 22 and 28 are preferably of lead and will lastindefinitely, while the pump cylinder is double-walled, so that in casethe outer wall IIC should rust or be eaten through the oil will beexcluded from the pump-cylinder by the second inner wall.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is
